    A Web-Based Tool for Analysing Normative Documents in English

    Full text link
    Our goal is to use formal methods to analyse normative documents written in English, such as privacy policies and service-level agreements. This requires the combination of a number of different elements, including information extraction from natural language, formal languages for model representation, and an interface for property specification and verification. We have worked on a collection of components for this task: a natural language extraction tool, a suitable formalism for representing such documents, an interface for building models in this formalism, and methods for answering queries asked of a given model. In this work, each of these concerns is brought together in a web-based tool, providing a single interface for analysing normative texts in English. Through the use of a running example, we describe each component and demonstrate the workflow established by our tool

    Extracting Formal Models from Normative Texts

    Full text link
    We are concerned with the analysis of normative texts - documents based on the deontic notions of obligation, permission, and prohibition. Our goal is to make queries about these notions and verify that a text satisfies certain properties concerning causality of actions and timing constraints. This requires taking the original text and building a representation (model) of it in a formal language, in our case the C-O Diagram formalism. We present an experimental, semi-automatic aid that helps to bridge the gap between a normative text in natural language and its C-O Diagram representation. Our approach consists of using dependency structures obtained from the state-of-the-art Stanford Parser, and applying our own rules and heuristics in order to extract the relevant components. The result is a tabular data structure where each sentence is split into suitable fields, which can then be converted into a C-O Diagram. The process is not fully automatic however, and some post-editing is generally required of the user. We apply our tool and perform experiments on documents from different domains, and report an initial evaluation of the accuracy and feasibility of our approach.Comment: Extended version of conference paper at the 21st International Conference on Applications of Natural Language to Information Systems (NLDB 2016). arXiv admin note: substantial text overlap with arXiv:1607.0148

    Rethinking network governance: new forms of analysis and the implications for IGR/MLG

    Our position is that network governance can be understood as a communicative arena. Networks, then, are not defined by frequency of interactions between actors but by sharing of and contest between different clusters of ideas, theories and normative orientations (discourses) in relation to the specific context within which actors operate. A discourse comprises an ensemble of ideas, concepts and causal theories that give meaning to and reproduce ways of understanding the world (Chouliaraki and Fairclough 1999). Consequently, network governance can be understood as the inherently political process through which discourses are produced, reproduced and transformed. Democratic network governance thus becomes the study of the way in which the core challenges of democratic practice are addressed – how is legitimacy awarded, by what mechanisms are decisions reached, and how is accountability enabled. Three approaches to the discursive analysis of democracy in network governance are considered - argumentation analysis, inter-subjectivity, and critical discourse analysis – and their implications for the study of intergovernmental relations and multi-level governance (IGR/MLG) are discussed. Case examples are provided. We conclude that the value for the study of MLG/IGR is to complement existing forms of analysis by opening up the communicative and ideational aspects of interactions between levels of government and other actors

    Web 2.0 and destination marketing: current trends and future directions

    Get PDF
    Over the last decade, destination marketers and Destination Marketing Organizations (DMOs) have increasingly invested in Web 2.0 technologies as a cost-effective means of promoting destinations online, in the face of drastic marketing budgets cuts. Recent scholarly and industry research has emphasized that Web 2.0 plays an increasing role in destination marketing. However, no comprehensive appraisal of this research area has been conducted so far. To address this gap, this study conducts a quantitative literature review to examine the extent to which Web 2.0 features in destination marketing research that was published until December 2019, by identifying research topics, gaps and future directions, and designing a theory-driven agenda for future research. The study’s findings indicate an increase in scholarly literature revolving around the adoption and use of Web 2.0 for destination marketing purposes. However, the emerging research field is fragmented in scope and displays several gaps. Most of the studies are descriptive in nature and a strong overarching conceptual framework that might help identify critical destination marketing problems linked to Web 2.0 technologies is missing

    SMEs and Certified Management Standards: The Effect of Motives and Timing on Implementation and Commitment

    Get PDF
    Existing research on certifiable management standards (CMS) and corporate social responsibility (CSR) tends to focus on large companies and is characterised by disagreement about the role of these standards as drivers of CSR. We contribute to the literature by shifting the analytical focus to the behaviour of small and medium-sized enterprises (SMEs) that subscribe to multiple CSR related standards. We argue that, in respect of motive and commitment, SMEs are not as different from large companies as the literature suggests, as they are guided by similar institutional and economic motives. Results, based on ISO 9001, ISO 14001 and OHSAS 18001 certified SMEs in Greece, demonstrate that later adopters are more susceptible to coercive and mimetic motives and are less likely to commit fully to the CMS requirements, while earlier adopters react to normative motives and considerations of internal efficiency gains and tend to carry out CMS requirements with greater diligence

    A framework for evaluating the effectiveness of flood emergency management systems in Europe

    Get PDF
    Calls for enhancing societal resilience to flooding are echoed across Europe alongside mounting evidence that flood risk will increase in response to climate change amongst other risk-enhancing factors. At a time where it is now widely accepted that flooding cannot be fully prevented, resilience discourse in public policy stresses the importance of improving societal capacities to absorb and recover from flood events. Flood emergency management has thus emerged as a crucial strategy in flood risk management. However, the extent to which emergency management supports societal resilience is dependent on the effectiveness of governance and performance in practice. Drawing from the extensive body of literature documenting the success conditions of so-called effective emergency management more broadly, this study formulates an evaluation framework specifically tailored to the study of Flood Emergency Management Systems (FEMS) in Europe. Applying this framework, this research performs a cross-country comparison of FEMS in the Netherlands, England, Poland, France, and Sweden. Important differences are observed in how FEMS have evolved in relation to differing contextual backgrounds (political, cultural, administrative and socio-economic) and exposures to flood hazard. Whereas the organization and coordination of actors are functioning effectively, other aspects of effective FEMS are relatively under-developed in several countries, such as provisions for institutional learning, recovery-based activities and community preparedness. Drawing from examples of good practice, this paper provides a critical reflection on the opportunities and constraints to enhancing the effectiveness of FEMS in Europe
